"Well," said Reg, "it's been an interesting time recently, or rather, a dull time. But dull for interesting reasons."

Our reading
An editorial interpretation.
Reg first calls the recent period interesting, corrects that to dull, then finds interest in the reasons for its dullness. Each turn complicates the one before it. The humour lies in this careful verbal repair, making even a description of boredom unexpectedly absorbing.
